neonnight, here is a link that you may find useful to help with your install.
If you do not want to get this "in depth" with the installation you can always look for an authorized Bazooka dealer in your area who can do the install for you. Once you find the correct wires install really is not that difficult. A Digital Multi Meter would be a great help, this will help you verify your constant 12v power and switched 12v. Again, if you have any questions or need anymore advice please post back.
